“Science, which is the logic of nature, demands proportion between the house and its foundation. Theology sometimes builds weighty structures on a doubtful base.”

“Even if all life on our planet is destroyed, there must be other life somewhere which we know nothing of. It is impossible that ours is the only world; there must be world after world unseen by us, in some region or dimension that we simply do not perceive. Even though I can't prove that, even though it isn't logical — I believe it.”

“We must mention the higher, nobler wealth, which does not belong to all, but to truly noble and divinely gifted men. This wealth is bestowed by wisdom through the doctrines and principles of ethic, logic and physic, and from these spring the virtues, which rid the soul of its proneness to extravagance, and engender the love of contentment and frugality, which will assimilate it to God. For God has no wants, He needs nothing, being in Himself all-sufficient to Himself, while the fool has many wants, ever thirsting for what is not there, longing to gratify his greedy and insatiable desire, which he fans into a blaze like a fire and brings both great and small within its reach. But the man of worth has few wants, standing midway between mortality and immortality.”

“A mathematician is not a man who can readily manipulate figures; often he cannot. He is not even a man who can readily perform the transformation of equations by the use of calculus. He is primarily an individual who is skilled in the use of symbolic logic on a high plane, and especially he is a man of intuitive judgment in the choice of the manipulative processes he employs.”

“The nation state is the product of that logic. In England … it was worked out to its final conclusion at the Henrician reformation, the event by which the English nation state was fully realised. All exertion of authority, whether the making or the enforcement of law, the taking of collective decisions of an executive (i. e. not legislable) character, the imposition and collection of taxes, the judgment of causes—in short, all duress brought to bear by the society upon the individual—proceeds from one source, and that source an internal and native one. The England of Henry VIII found it impossible that its laws should be made, that its causes should be judged, or that a revenue should be procured from it by an external authority. In other words, there was no such thing as external authority: the expression was a contradiction in terms… There is a name for appealing over the head of the Crown to an authority outside the realm, and that name is treason. The word may be disused, but the thing is not; and the penalties of praemunire, which those guilty of it formerly incurred, were not disproportionate to its seriousness.”

“We are not ostriches, and cannot believe that if we refuse to look at what we do not wish to see, it will not exist. This is especially the case when what we do not wish to see is what we wish to eat. If it were really indispensable, or, if not indispensable, at least in some way useful! But it is quite unnecessary … And this is continually being confirmed by the fact that young, kind, undepraved people — especially women and girls — without knowing how it logically follows, feel that virtue is incompatible with beefsteaks, and, as soon as they wish to be good, give up eating flesh.”

“One of the reasons why our people are alive and flourishing, and have avoided many of the troubles that have fallen to less happy nations, is because we have never been guided by logic in anything we have done. If you will only do as I have done—study the history of the growth of the Constitution from the time of the Civil War until the Hanoverians came to the Throne—you will see what a country can do without the aid of logic, but with the aid of common sense.”

“What justice also demands, inspired by the same feeling, is the punishment of the guilty and effective guaranties against an active return of the spirit by which they were tempted; and it is logical to demand that these guaranties should be given, above all, to the nations that have been, and might again be most exposed to aggressions or threats, to those who have many times stood in danger of being submerged by the periodic tide of the same invasions. What justice banishes is the dream of conquest and imperialism, contempt for national will, the arbitrary exchange of provinces between states as though peoples were but articles of furniture or pawns in a game. The time is no more when diplomatists could meet to redraw with authority the map of the empires on the corner of a table. If you are to remake the map of the world it is in the name of the peoples, and on condition that you shall faithfully interpret their thoughts, and respect the right of nations, small and great, to dispose of themselves, and to reconcile it with the right, equally sacred, of ethnical and religious minorities - a formidable task, which science and history, your two advisers, will contribute to illumine and facilitate.”

“The hypothesis you refer to as God, though not disprovable by logic alone, is unnecessary for the following reason.
If you assume that the universe can be quote explained unquote as the creation of an entity known as God, he must obviously be of a higher degree of organization than his product. Thus you have more than doubled the size of the original problem, and have taken the first step on a diverging infinite regress. William of Ockham pointed out as recently as your fourteenth century that entities should not be multiplied unnecessarily. I cannot therefore understand why this debate continues.”

“Economics is a science of thinking in terms of models joined to the art of choosing models which are relevant to the contemporary world. It is compelled to be this, because, unlike the typical natural science, the material to which it is applied is, in too many respects, not homogeneous through time. The object of a model is to segregate the semi-permanent or relatively constant factors from those which are transitory or fluctuating so as to develop a logical way of thinking about the latter, and of understanding the time sequences to which they give rise in particular cases.
Good economists are scarce because the gift for using "vigilant observation" to choose good models, although it does not require a highly specialised intellectual technique, appears to be a very rare one.”

The dialectic is an amusing mechanism which guides us / in a banal kind of way / to the opinions we had in the first place. Does anyone think that, by a minute refinement of logic, he has demonstrated the truth and established the correctness of these opinions? Logic imprisoned by the senses is an organic disease”

“There is another and very important ground for standardization and that is the desirability of having parts interchangeable. Standards of exchange have long been in general use, and these have, most usually, been fixed with a view to convenient use rather than on a scientific basis. The units of weight and measure are examples of this form of standard. They may not even be the most logical, or most convenient, but once established they can, in general, be changed only by slow degrees, if at all.”

“There certainly seems to be a strong correlation between religion and insanity. I’ve read a few papers comparing the logical and psychological aptitude of strong believers vs those with little or no faith at all, and the trends there all seem to be in our favor, but not to the point that religion causes the disorder. I think certain mental disorders can prompt religious beliefs, but that’s a different claim. I think religion provides a haven to conceal quite a lot of cognitive and psychiatric disorders as well as some social dysfunctions. But that doesn’t mean religion is a mental illness, regardless how accurate analogies of the God virus might be. I think there are circumstances when religion can be treated as a psychological condition, especially when it is the result of detrimental conditioning, but I wouldn’t confuse that with a psychiatric malady, which (I think) would have to be physiological/chemical.”

“According to a stagist conception of progressive history (which is usually blind to its implicit teleology), the work of figures like Foucault, Derrida and other cutting-edge French theorists is often intuitively affiliated with a form of profound and sophisticated critique that presumably far surpasses anything found in the socialist, Marxist or anarchist traditions. It is certainly true and merits emphasis that the Anglophone reception of French theory, as John McCumber has aptly pointed out, had important political implications as a pole of resistance to the false political neutrality, the safe technicalities of logic and language, or the direct ideological conformism operative in the McCarthy-supported traditions of Anglo-American philosophy. However, the theoretical practices of figures who turned their back on what Cornelius Castoriadis called the tradition of radical critique—meaning anti-capitalist and anti-imperialist resistance—surely contributed to the ideological drift away from transformative politics. According to the spy agency itself, post-Marxist French theory directly contributed to the CIA’s cultural program of coaxing the left toward the right, while discrediting anti-imperialism and anti-capitalism, thereby creating an intellectual environment in which their imperial projects could be pursued unhindered by serious critical scrutiny from the intelligentsia.”

“We are left with a budget of paradoxes. Given the seeming logic of the proposed classification of right-wing polities—with nationalism, hierarchical political structures, and charismatic leadership as defining properties— both fascism and Marxism-Leninism would seem to be political products of right-wing extremism.

There’s a part of a man’s mind that can only relax and go to sleep when he’s with a woman, and that part gets tired of always being tensely awake. It gives orders in so loud a voice that it often drowns out the other components. But when the loud one is asleep at last, the others regain control and chart a new course.” He grinned. “No equilibrium is possible. If you don’t want to put up with the constant seesawing, you must either starve the logical components or bind, gag and lock away in a cellar that one insistent one.”

“The contemporary mathematical and symbolic logic is certainly very different from its classical predecessor, but they share the radical opposition to dialectical logic. In terms of this opposition, the old and the new formal logic express the same mode of thought. it is purged from that “negative” which loomed so large at the origins of logic and of philosophic thought — the experience of the denying, deceptive, falsifying power of the established reality. And with the elimination of this experience, the conceptual effort to sustain the tension between “is” and “ought”, and to subvert the established universe of discourse in the name of its own truth is likewise eliminated from all thought which is to be objective, exact, and scientific. For the scientific subversion of the immediate experience which establishes the truth of science as against that of immediate experience does not develop the concepts which carry in themselves the protest and the refusal. The new scientific truth which they oppose to the accepted one does not contain in itself the judgment that condemns the established reality. … In contrast, dialectical thought is and remains unscientific to the extent to which it is such judgment.”

“We know, since the theory of relativity at least, that empirical sciences are to some degree free in defining dynamical concepts or even in assuming laws, and that only a system as a whole which includes concepts, coordinating definitions, and laws can be said to be either true or false, to be adequate or inadequate to empirical facts. This "freedom," however, is a somewhat doubtful gift. The manifold of possibilities implies uncertainty, and such uncertainty can become rather painful in a science as young as psychology, where nearly all concepts are open and unsettled. As psychology approaches the state of a logically sound science, definitions cease to be an arbitrary matter. They become far-reaching decisions which presuppose the mastering of the conceptual problems but which have to be guided entirely by the objective facts.”

An hallucination is not, strictly speaking, manufactured in the brain; it is received by the brain, like any 'real' sense datum, and the patient act in response to this to-him-very-real perception of reality in as logical a way as we do to our sense data. In any way to suppose he only 'thinks he sees it' is to misunderstand totally the experience of psychosis."”

“I’m your apprentice!” Simon protested. “When are you going to teach me something?”
“Idiot boy! What do you think I’m doing? I’m trying to teach you to read and to write. That’s the most important thing. What do you want to learn?”
“Magic!” Simon said immediately. Morgenes stared at him.
“And what about reading…?” the doctor asked ominously.
Simon was cross. As usual, people seemed determined to balk him at every turn. “I don’t know,” he said. What’s so important about reading and letters, anyway? Books are just stories about things. Why should I want to read books?”
Morgenes grinned, an old stoat finding a hole in the henyard fence. “Ah, boy, how can I be mad at you…what a wonderful, charming, perfectly stupid thing to say!” The doctor chuckled appreciatively, deep in his throat.
“What do you mean?” Simon’s eyebrows moved together as he frowned. “Why is it wonderful and stupid?”
“Wonderful because I have such a wonderful answer,” Morgenes laughed. Stupid because…because young people are made stupid, I suppose—as tortoises are made with shells, and wasps with stings—it is their protection against life’s unkindnesses.”
“Begging your pardon?” Simon was totally flummoxed now.
“Books,” Morgenes said grandly, leaning back on his precarious stool, “—books are magic. That is the simple answer. And books are traps as well.”
“Magic? Traps?”
“Books are a form of magic—” the doctor lifted the volume he had just laid on the stack, “—because they span time and distance more surely than any spell or charm. What did so-and-so think about such-and-such two hundred years agone? Can you fly back through the ages and ask him? No—or at least, probably not.
But, ah! If he wrote down his thoughts, if somewhere there exists a scroll, or a book of his logical discourses…he speaks to you! Across centuries! And if you wish to visit far Nascadu or lost Khandia, you have also but to open a book….”

Morgenes leaned forward, waggling the leather-bound volume under Simon’s nose. “A piece of writing is a trap,” he said cheerily, “and the best kind. A book, you see, is the only kind of trap that keeps its captive—which is knowledge—alive forever. The more books you have,” the doctor waved an all-encompassing hand about the room, “the more traps, then the better chance of capturing some particular, elusive, shining beast—one that might otherwise die unseen.”

“The central psychological endeavor of Kierkegaard may be summed up under the heading of the question he pursued relentlessly: How can one become an individual? The individual was being swallowed up on the rational side by Hegel's vast logical "absolute Whole," on the economic side by the increasing objectification of the person, and on the moral and spiritual side by the soft and vapid religion of his day. Europe was ill, and was to become more so, not because knowledge or techniques were lacking but because of the want of passion, commitment.

“A baby is shown sitting on the floor. He appears to be about a year and a half old. Incidentally, he is a very plain baby. Strewn about him on the floor are the toys that he has been playing with. There are a ball, a rattle, a ring, a doll, a bell and a pair of roller-skates. Evidently, the candidate is supposed to be aghast at the roller-skates in the possession of such a small child.
The man who drew that picture had evidently never furnished playthings for a small child. I can imagine nothing that would delight a child of a year and a half more than a pair of roller-skates to chew and spin and hit himself in the face with. They could also be dropped on Daddy when Daddy was lying on the floor in an attempt to be sociable. Of all the toys arranged before the child, the roller-skates are the most logical. … That is my great trouble in taking tests and examinations of any kind.

“Logic is not concerned with human behavior in the same sense that physiology, psychology, and social sciences are concerned with it. These sciences formulate laws or universal statements which have as their subject matter human activities as processes in time. Logic, on the contrary, is concerned with relations between factual sentences (or thoughts). If logic ever discusses the truth of factual sentences it does so only conditionally, somewhat as follows: if such-and-such a sentence is true, then such-and-such another sentence is true. Logic itself does not decide whether the first sentence is true, but surrenders that question to one or the other of the empirical sciences.”

“Because demography is concerned with human affairs and human populatlons it is possible, in principle, to consider demography as a sub-ﬁeld of many other subjects. It provided the scope of any particular subject-ﬁeld like anthropology, genetics, ecology, economics, sociology, etc., and is deﬁned in a sufﬁciently comprehensive manner. While not denying the possibility of considering demography as a sub-ﬁeld of one or another subject, at least for certain special purposes, it is suggested that demography should be logically viewed as the totality of convergent and inter-related factors and topics which (although these could be, spearately, the concern of many diﬂ'erent subjects like genetics and anthropology, sociology, education, psychology. economics, social and political affairs etc.) jointly, together with their mutual inter-actions, form the determinants as well as the consequences of growth (or decline), changes in composition, territorial movements, and social mobility of population in different geographical regions or in the world as a whole, at any given period of time, or over diﬂ'erent periods of time. Such a view would supply an aggregative, inter-related, and mutually interacting system of all those factors which have any inﬂuence over, or are inﬂuenced by, demographic or population changes over space and time.”

“Contemporary philosophers have exercised themselves with the problem of our knowledge of other minds. Enmeshed in the dogma of the ghost in the machine, they have found it impossible to discover any logically satisfactory evidence warranting one person in believing that there exist minds other than his own. I can witness what your body does, but I cannot witness what your mind does, and my pretensions to infer from what your body does to what your mind does all collapse, since the premises for such inferences are either inadequate or unknowable.”

“Let no one charge us with capricious inconsistency in our actions against Albinus, and let no one think that I am disloyal to this alleged friend or lacking in feeling toward him. 2. We gave this man everything, even a share of the established empire, a thing which a man would hardly do for his own brother. Indeed, I bestowed upon him that which you entrusted to me alone. Surely Albinus has shown little gratitude for the many benefits I have lavished upon him. 3. Now |87 he is collecting an army to take up arms against us, scornful of your valor and indifferent to his pledge of good faith to me, wishing in his insatiable greed to seize at the risk of disaster that which he has already received in part without war and without bloodshed, showing no respect for the gods by whom he has often sworn, and counting as worthless the labors you performed on our joint behalf with such courage and devotion to duty. 4. In what you accomplished, he also had a share, and he would have had an even greater share of the honor you gained for us both if he had only kept his word. For, just as it is unfair to initiate wrong actions, so also it is cowardly to make no defense against unjust treatment. Now when we took the field against Niger, we had reasons for our hostility, not entirely logical, perhaps, but inevitable. We did not hate him because he had seized the empire after it was already ours, but rather each one of us, motivated by an equal desire for glory, sought the empire for himself alone, when it was still in dispute and lay prostrate before all. 5. But Albinus has violated his pledges and broken his oaths, and although he received from me that which a man normally gives only to his son, he has chosen to be hostile rather than friendly and belligerent instead of peaceful. And just as we were generous to him previously and showered fame and honor upon him, so let us now punish him with our arms for his treachery and cowardice. 6. His army, small and island-bred, will not stand against your might. For you, who by your valor and readiness to act on your own behalf have been victorious in many battles and have gained control of the entire East, how can you fail to emerge victorious with the greatest of ease when you have so large a number of allies and when virtually the entire army is here. Whereas they, by contrast, are few in number and lack a brave and competent general to lead them. 7. Who does not know Albinus' effeminate nature? Who does not know that his way |88 of life has prepared him more for the chorus than for the battlefield? Let us therefore go forth against him with confidence, relying on our customary zeal and valor, with the gods as our allies, gods against whom he has acted impiously in breaking his oaths, and let us be mindful of the victories we have won, victories which that man ridicules.”

“Proof that the penis is a much later development than the female vulva is found in the evidence that the male himself was a late mutation from an original female creature. For man is but an imperfect female. Geneticists and physiologists tell us that the Y chromosome that produces males is a deformed and broken X chromosome — the female chromosome. All women have two X chromosomes, while the male has one X derived from his mother and one Y from his father. It seems very logical that this small and twisted Y chromosome is a genetic error — an accident of nature, and that originally there was only one sex — the female.”

Consequently different art expressions even in a single period are not only logical but a tribute to the general development of art.

“The creation and implementation of integrated information systems involves a variety of collaborators including people from specialist departments, informatics, external advisers and manufacturers. They need clear rules and limits within which they can process their individual sub-tasks, in order to ensure the logical consistency of the entire project. Therefore, an architecture needs to be established to determine the components that make up the information system and the methods to be used to describe it. The ARIS architecture developed in this book is described in concrete terms as an information model within the entity-relationship approach. This information model provides the basis for the systematic and rational application of methods in the development of information systems. It also serves as the basis for a repository in which the enterprise's application - specific data, organization and function models can be stored. The ARIS architecture constitutes a framework in which integrated applications systems can be developed, optimized and converted into EDP - technical implementations. At the same time, it demonstrates how business economics can examine and analyze information systems in order to translate their contents into EDP-suitable form.”

Even now that we know that Euclidean geometry is (in some sense) not quite true? Is it not good to know what follows from what, even if it is not necessarily FAPP? Suppose for example that quantum mechanics were found to resist precise formulation. Suppose that when formulation beyond FAPP was attempted, we find an unmovable finger obstinately pointing outside the subject, to the mind of the observer, to the Hindu scriptures, to God, or even only Gravitation? Would that not be very, very interesting?”

“First let us ask whether our wealth-creating agencies, particular that of industry, are to be based upon private enterprise of policy management. I can not see how any intelligent observer can have any possible faith in the capacity of political management to provide either stability or progress if it should set out to operate the agencies of wealth creation, particularly industry. It is my firm conviction that any form of 'Government Regulation of Business' is bound to result in an ever-increasing interference with the broad exercise of initiative - the very foundation of the American system. That is the natural evolution of bureaucracy. If that be so, might not the ultimate logical result be the necessity for the socialization of industry through the break down of the profit system induced by the accumulative effect of the ever-increasing political management. We do not need to go far afield to see definite evidences of that possibility”

“Thud. My eyes are open. It is four-thirty in the morning, one morning, and my dry eyes click in their sockets, awake before the birds. There is no light. The eye strains for logic, some play of form. I have been dreaming of wind. The tree outside my window stands silent. I listen to the breathing of the man lying beside me. I know where I am. I am awake. I am alive. Am I tethered to earth only by this fragile breath? A strawful of breath at best. Yet this is the breath that patients beg, their hands gripping the edges of mattresses; this is the breath that wrestles trees, that brings down all the leaves in the Third Act. We know where the car is parked. We know, word-for-word, the texts of plays. We have spoken, in proximity to one another, over years, sentences, hundreds of thousands of sentences—bright, grave, fallible, comic, perishable—perhaps eternal? I don’t know. Where does the wind go? When will the light come? We will have hotcakes for breakfast. How can I protect this...? My church teaches me I cannot. And I believe it. I turn the pillow to its cool side. Then rage fills me, against the cubist necessity of having to arrange myself comically against orthodoxy, against having to wonder if I will offend, against theology that devises that my feeling for him, more than for myself, is a vanity. My brown paradox: The church that taught me to understand love, the church that taught me well to believe love breathes—also tells me it is not love I feel, at four in the morning, in the dark, even before the birds cry. Of every hue and caste am I.”

“Ever since the Industrial Revolution, Western society has benefited from science, logic, and reductionism over intuition and holism. Psychologically and politically we would much rather assume that the cause of a problem is “out there,” rather than “in here.” It’s almost irresistible to blame something or someone else, to shift responsibility away from ourselves, and to look for the control knob, the product, the pill, the technical fix that will make a problem go away.
Serious problems have been solved by focusing on external agents — preventing smallpox, increasing food production, moving large weights and many people rapidly over long distances. Because they are embedded in larger systems, however, some of our “solutions” have created further problems. And some problems, those most rooted in the internal structure of complex systems, the real messes, have refused to go away.
Hunger, poverty, environmental degradation, economic instability, unemployment, chronic disease, drug addiction, and war, for example, persist in spite of the analytical ability and technical brilliance that have been directed toward eradicating them. No one deliberately creates those problems, no one wants them to persist, but they persist nonetheless.
That is because they are intrinsically systems problems-undesirable behaviors characteristic of the system structures that produce them. They will yield only as we reclaim our intuition, stop casting blame, see the system as the source of its own problems, and find the courage and wisdom to restructure it.”

Already they had before them the examples of Francis Bacon (speculative and descriptive) and Hobbes (quantitative and qualitative).

Arthur Schopenhauer’s similar groups were called pure and empirical, Wilhelm Wundt in 1887 called them formal and empirical, Globot mathematical and theoretical, and the St. Louis Congress of Arts and Sciences (1904) normative and physical.”

“I am to show you, too, that in the world of eternal free-agents, the Divine offices called creation and regeneration not only survive, but are transfigured; that in this transfiguration they are merged in one, so that regeneration is implicit in creation, and becomes the logical spring and aim of creation, while creation itself thus insures both generation and regeneration—the existence of the natural order within the spiritual or rational, and subject to this, and the consequent gradual transformation of the natural into the image of the spiritual: a process never to be interrupted, however devious, dark, or often retrograde, its course may be. I am to show you all this by the light of Final Cause, which is to take the place of the less rational category of Efficient Causation, since—let it be repeated — this last cannot operate to sustain moral relationship, and since moral values, measured in real freedom, are for the conscience and the new theology the measure of all reality.”

“Suppose I think, after doing my accounts, that I have a large balance at the bank. And suppose you want to find out whether this belief of mine is “wishful thinking.” You can never come to any conclusion by examining my psychological condition. Your only chance of finding out is to sit down and work through the sum yourself. When you have checked my figures, then, and then only, will you know whether I have that balance or not. If you find my arithmetic correct, then no amount of vapouring about my psychological condition can be anything but a waste of time. If you find my arithmetic wrong, then it may be relevant to explain psychologically how I came to be so bad at my arithmetic, and the doctrine of the concealed wish will become relevant—but only after you have yourself done the sum and discovered me to be wrong on purely arithmetical grounds. It is the same with all thinking and all systems of thought. If you try to find out which are tainted by speculating about the wishes of the thinkers, you are merely making a fool of yourself. You must first find out on purely logical grounds which of them do, in fact, break down as arguments. Afterwards, if you like, go on and discover the psychological causes of the error.”

“Adolf Hitler took Darwin's evolutionary philosophy to its logical conclusions.”

“I suppose I would be a logical choice to play the Doctor just because Giles, my character in Buffy, has the same light and dark sides and quirkiness as Doctor Who.”

“Finally, the claim that we equated punctuated equilibrium with saltation makes no sense within the logical structure of our theory — so, unless we are fools, how could we ever have asserted such a proposition? Our theory holds, as a defining statement, that ordinary allopatric speciation, unfolding gradually at microevolutionary scales, translates to punctuation in geological time.”

“My father regarded nationalism, including Zionism, as an evil and although he never attempted to convince me of his views, his logic, here, was inescapable.”

“I have endeavoured… to present the principles and applications of Symbolical, in immediate sequence to those of Arithmetical, Algebra, and at the same time to preserve that strict logical order and simplicity of form and statement which is essential to an elementary work. This is a task of no ordinary difficulty, more particularly when the great generality of the language of Symbolical Algebra and the wide range of its applications are considered, and this difficulty has not been a little increased, in the present instance, by the wide departure of my own views of its principles from those which have been commonly entertained.”

“Let me start a different/ analysis by recalling an idea from Max Weber. He characterized cultural modernity as the separation of the substantive reason expressed in religion and metaphysics into three autonomous spheres. They are science, morality and art. These came to be differentiated because the unified world-views of religion and metaphysics fell apart. Since the 18th century, the problems inherited from these older world-views could be arranged so as to fall under specific aspects of validity: truth, normative rightness, authenticity and beauty. They could then be handled as questions of knowledge, or of justice and morality, or of taste. Scientific discourse, theories of morality, Jurisprudence, and the production and criticism of art could in turn be institutionalized. Each domain of culture could be made to correspond to cultural professions in which problems could be dealt with as the concern of special experts. This professionalized treatment of the cultural tradition brings to the fore the intrinsic structures of each of the three dimensions of culture. There appear the structures of cognitive-instrumental, of moral-practical and of aesthetic-expressive rationality, each of these under the control of specialists who seem more adept at being logical in these particular ways than other people are. As a result, the distance grows between the culture of the experts and that of the larger public. What accrues to culture through specialized treatment and reflection does not immediately and necessarily become the property of everyday praxis. With cultural rationalization of this sort, the threat increases that the life-world, whose traditional substance has already been devalued, will become more and more impoverished.”

“I reduced painting to its logical conclusion and exhibited three canvases: red, blue and yellow. I affirmed: it's all over. Basic colors. Every plane is a plane and there is to be no representation.”

Alexander Rodchenko (1891–1956) Russian artist and photographer

Quote in: 'The Death of Painting'; from the MoMA-website: Interactives: texts https://www.moma.org/interactives/exhibitions/1998/rodchenko/texts/death_of_painting.html Rodchenko is looking back: in 1921 he executed what were arguably some of the first true monochromes (artworks of one color; source, Wikipedia:Rodchenko)

“Dialectical logic is loyal to the contradictions, not by the reasoning of “on the one hand and the other” but by tracing the contradictions to their fractured source.”
